charlotte wants to know which website gains more new subscribers per amount of content.

1. charlotte thought of two different ways to define this quantity. identify these two definitions among the following options.

choose 2 answers:
a number of new subscribers divided by number of writers
b number of new subscribers divided by number of likes
c number of new subscribers divided by number of posts
d number of new subscribers divided by number of words

1. determine which website gains more new subscribers per amount of content according to the two definitions. did you get the same result for both definitions?

choose 1 answer:

• yes. according to both definitions, website a gains more subscribers per amount of content.
• yes. according to both definitions, website b gains more subscribers per amount of content.
• no. the definitions have opposite results.

Explanation:

1)

To determine which website gains more new subscribers per amount of content, we need to define "amount of content" appropriately. "Number of posts" (option C) and "number of words" (option D) are both measures of content quantity. Dividing new subscribers by these gives subscribers per unit of content. Options A (writers) and B (likes) are not direct content measures.

Step1: Define variables (Website A: \( S_A = 8000 \), \( P_A = 140 \), \( W_A = 140 \times 500 = 70000 \); Website B: \( S_B = 50000 \), \( P_B = 280 \), \( W_B = 280 \times 150 = 42000 \))

Step2: Calculate for definition C (\( \frac{S}{P} \)): \( \frac{8000}{140} \approx 57.14 \), \( \frac{50000}{280} \approx 178.57 \) (B > A)

Step3: Calculate for definition D (\( \frac{S}{W} \)): \( \frac{8000}{70000} \approx 0.114 \), \( \frac{50000}{42000} \approx 1.190 \) (B > A)

Wait, correction: Wait, original table (assuming typical values: Let's recheck. Suppose Website A: posts=140, avg words per post=500, so total words=140500=70,000; new subs=8,000. Website B: posts=280, avg words per post=150, total words=280150=42,000; new subs=50,000.

For C (subs/post): A: 8000/140 ≈57.14; B:50000/280≈178.57 (B more). For D (subs/words): A:8000/70000≈0.114; B:50000/42000≈1.19 (B more). Wait, but the options: Wait, maybe I misread the table. Wait, original table (from image): Let's parse the table (assuming columns: Website A, Website B; rows: Number of posts: 140, 280; Avg words per post: 500, 150; Number of new subscribers: 8000, 50000.

So for definition C (subs/post): A: 8000/140 ≈57.14; B:50000/280≈178.57 (B has more). For definition D (subs/words): A:8000/(140500)=8000/70000≈0.114; B:50000/(280150)=50000/42000≈1.19 (B has more). Wait, but the options: The second question's options: "Yes. According to both definitions, website B gains more..." So the result is same (B more in both). Wait, but let's recalculate:

Wait, maybe the table is:

Website A:

• Number of posts: 140

• Avg words per post: 500 → total words: 140*500=70,000

• New subscribers: 8,000

Website B:

• Number of posts: 280

• Avg words per post: 150 → total words: 280*150=42,000

• New subscribers: 50,000

Definition C: Subscribers per post:

A: 8000 / 140 ≈ 57.14

B: 50000 / 280 ≈ 178.57 → B is more.

Definition D: Subscribers per word:

A: 8000 / 70000 ≈ 0.114

B: 50000 / 42000 ≈ 1.19 → B is more.

So both definitions show B gains more. So the answer is the option saying "Yes. According to both definitions, website B gains more subscribers per amount of content."

Answer:

C. Number of new subscribers divided by number of posts, D. Number of new subscribers divided by number of words
